When you place a new boat in 15w41b underwater, the boat sinks and when you right click it it get in, you are teleported up and away from it. The boats do not float up to the surface.
Is this intentional?

I can confirm.
Confirmed for 15w42a.
Confirmed, and boats can no longer rise up water levels so all boat elevators, log flume rides and upstream river travel are all broken now
EDIT Confirmed for 15w42a
Still broken in 15w44a

Still broken in 15w46a

15w47a
Confirmed for 15w50a.
Still broken in 16w02a

Still in 16w03a.
If you get water in the boat, you will sink.
Grum .Your boat mechanics and physics are all wrong ! water weighs 28.316847 kg / 0.0283168 cubic meter or in Imperial approx 62 lbs per cubic foot
Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics.
All boat builders build their boats positively buoyant . They are designed to float if filled with water or capsized . What is the minecraft boat made from ? Lead !
Version 1.9 Pre 2 out today . Boats are broken . Have not found a way to traverse up 1 block of water . Are you waiting for the modding community to fix what you can't ? Engineers play this game as well , we're scratching our heads , we just don't understand what your trying to do with the boat .
Lets build a minecraft boat , 6'(L) x 4'(w) x 2'(H) = 48 cubic feet , 48 cubic feet of water = approx 62 lbs x 48 = 2,976 lbs . The weight of the boat , its contents and passengers would have to exceed 2,976 lbs , to displace 48 cubic feet of water and sink . Since , when the boat sinks , it ejects its passengers and the boat is built to be positively buoyant . The boat can not sink . I can see it capsize or floating at the waterline . The boat travels down a gradient of water fine , It just can't travel up a gradient . I was told , this is the way it's supposed to be and the final release to be on Feb 25 . I Just want to know will you be releasing the final version with broken boats ?

You explanation makes sense, I personally think it will be pretty annoying to remove the boats once the start sinking so you will end with a ton of sunken boats at the ground of the ocean.
What you are talking about at the end is probably covered by MC-91206 (if I understood you correctly)

Please change the "duplicates" link to MC-91206 to "relates to"
This was the most stupidest change. How can you talk about realistic physics when we're in a game made of blocks where I can teleport to kill a dragon? And you're changing the behavior of boats saying that if boats fill with water, they sink, as an act of making it more realistic? This is the perfect reason why I should downgrade my server to 1.8. Thanks a bunch Microsoft... you ruined Windows 10 and now you're ruining Minecraft. :/
